It is usually assumed that each cooperator contributes equally to different public pools in spatial goods game. However, it more reasonable invest differently according individual investment preference. In this paper, an extended game, which cooperators contribute the groups preference, developed. The preference of a characterized by fraction from his/her own memory about group and intensity represented tunable parameter α. well-mixed population structured are analyzed under mechanism. shown can give rise coordination. Moreover, extensive numerical simulation results show with increasing density or length, proportion cooperation increase monotonously. This because could help resist invasion defectors. Compared basic version, new mechanism able promote effectively. Our research may provide valuable insight for further exploring nature real world.
